Step-by-step explanation:
I just used desmos easy to use and you understand how graphs work more.
Which integer represents 8ºC below 0?
8ºC below 0 is -8ºC (negative eight degrees celsius).
Below means subtract. 0 - 8 = -8.

219÷2=
can you guys plz help me I need to find the estimate.
Answer:
110
Step-by-step explanation:
219 divided by 2 equals 109.5, so you basically just round to the nearest whole number. You should get 110, thus, your answer. Of course, you could just leave it as 109.5, but if you want it estimated, or simplified, the information above should help.

For values of h very close to 0, which function best approximates (tan(x+5)-tan x) / h
Answer:
[tex]sec^2(x)[/tex]
Step-by-step explanation:
This just means, what is the derivative of tan(x)The function that best approximates the given situation is sec²x.
We have to find
[tex]\lim_{h \to\00} \frac{tan(x+h)-tan x}{h}[/tex]
Since the given expression reduces to 0/0 form when we apply the limits
So, let us apply the L'hospital rule
What is the L'hospital rule to find a limit?L'Hospital's Rule tells us that if we have an indeterminate form 0/0 or ∞/∞ all we need to do is differentiate the numerator and differentiate the denominator and then take the limit.
So, after differentiating the numerator as well as the denominator of the given expression with respect to h we get
[tex]\lim_{h \to\00} \frac{sec^2(x+h)-0}{1}[/tex]
[tex]= lim_{h \to\00} \frac{sec^2(x+0)}{1}\\\\= sec^2x[/tex]
Therefore, the function that best approximates the given situation is sec²x.

PLZ PLZ PLZ HELP I WILL GIVE BRAINLIEST PLZ HELP AND READ ALL QUESTIONS REMEMBER GOD IS GOOD.
Answer:
1) The amount the family spent on pizza is $300
2) The amount the family spent on soda is $43.2
3) The amount the family spent in all is $343.2
Step-by-step explanation:
The number of pizzas bought by the family = 24
The price of each pizza = $12.50
The number of bottles of soda the family bought = 36
The price of each bottles of soda = $1.20
1) The amount the family spent on pizza = 24 × $12.50 = $300
2) The amount the family spent on soda = 36 × $1.20 = $43.2
3) The amount the family spent in all = The amount the family spent on pizza + The amount the family spent on soda
∴ The amount the family spent on soda = $300 +$43.2 = $343.2.

What is the simplest form of the expression (14.2a + 9.8b) – (13.1b – 0.2a) – (3.7a + 4.8b)?
A. 10.7a – 8.1b
B. 10.7a + 27.7b
C. 18.1a - 8.1b
D. 18.1a + 27.7b
Answer:
A) 10.7a - 8.1b
Step-by-step explanation:
(14.2a + 9.8b) - (13.1b - 0.2a) - (3.7a + 4.8b)
Combine like terms.
(14.2a + 0.2a - 3.7a) = 10.7a
(9.8b - 13.1b - 4.8b) = -8.1b
Answer:
10.7a – 8.1b

Consider the line y = 4x-3.
Find the equation of the line that is perpendicular to this line and passes through the point (3, -3).
Find the equation of the line that is parallel to this line and passes through the point (3, -3).
Answer:
perpendicular line: y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]
parallel line: y = 4x - 15
Step-by-step explanation:
Perpendicular line:
A perpendicular line to y = 4x-3 would have a slope that is the negative reciprocal (flip the fraction and add a negative sign). The negative reciprocal of 4 is - [tex]\frac{1}{4}[/tex].
Now that we have our slope, we can plug the given point of (3, -3) into the slope-intercept equation to find b.
-3 = - [tex]\frac{1}{4}[/tex](3) + b
-3 = - [tex]\frac{3}{4}[/tex] + b
Add [tex]\frac{3}{4}[/tex] to each side of the equation to isolate b.
-[tex]\frac{9}{4}[/tex] = b
Now we can write our equation, y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]
Parallel Line:
A parallel line to y = 4x-3 has the same slope. To find the equation, plug the slope and given point (3, -3) into the slope intercept equation and solve for b.
-3 = 4(3) + b
-15 = b
Now you can write the equation, y= 4x -15
Solve the following equation for x.
-4x = 28
Answer:
The answer is x=-7

To find the x divide both side by -4
-4x = 28
-4x/-4=28/-4
x= -7

Answer: [tex]y=\frac{1}{2} x+2[/tex]
Step-by-step explanation:
The format for these equations are y=mx+b. Find the slope, which is the change in y over the change in x. When you apply this formula, you get 1/2. To find the y-intercept, just count from the origin to the place the line meets the y-axis, which is 2. Putting it together, you get the equation [tex]y= \frac{1}{2}x+2[/tex]

Write an equation of the line graphed below in slope-intercept form.
The equation of the line is y = (2/3)x -1
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
From the given graph, we have two points (0, 1) and (3,3)
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
y - 1= (3 -1 ) / (3 -0) x (x -0)
y = (2/3)x -1
The equation of the line is;
y = (2/3)x -1 {equation 1}
Slope intercept form of a line is
y = mx + b {equation 2} ,
where m is the slope and b is the y-intercept.
On comparing the equation (1) and (2) we get
It means,
Slope = 2/3
y-intercept = -1
Therefore, the equation of the line is y = (2/3)x -1

Answer:
5%
Step-by-step explanation:
Answer:
40%
Step-by-step explanation:
using the box method,
multiply 9 × 100
= 900 and divide 900 by 15
900 ÷ 15 = 60%
60% is the amount of pitches he hit
100% - 60% = 40%
he missed 40%

A graphic artist created the design for a rectangular poster. The design is 12 inches by 9 inches. The poster is 48 inches by 36 inches
What scale factor did the graphic artist use to create the design?
Answer:
4
Step-by-step explanation:
Step one:
given data
The design is 12 inches by 9 inches.
[tex]length = 12 in\\\\width = 9 in[/tex]
The poster is 48 inches by 36 inches
[tex]length = 48in\\\\width = 36 in[/tex]
Step two:
divide the dimension of the poster by the dimension of the design to get the scale factor
[tex]L= 48/12= 4\\\\W= 36/9= 4[/tex]
Hence the scale factor is 4

Paula can create number of possible ways of pictures are 35!.
What is a permutation?A permutation is defined as a mathematical process which determines the number of different arrangements in a set of objects when the order of the sequential arrangements.
Given that Paula has 35 unique puzzle pieces
So, the method of organizing possible pictures can she create dependent on each other to succeed.
There is an arrangement process
It is equal to the permutation of 35 numbers
⇒ ³⁵P₃₅
The formula of ⁿPₓ = n!/(n-x)!
⇒ 35!/(35-35)!
⇒ 35!/0! [∵ 0! = 1]
⇒ 35!
Hence, Paula can create number of possible ways of pictures are 35!.

Which equation combines with the given equation solution x = 3 and y = 9? X + 2y = 21 A. 4x + 6y = 64 B. 2x + y = 36 C. 4x + y = 21 D. -3x + 4y = 33 E. 3x + 2y = 28
Answer:
C. 4x + y = 21
Step-by-step explanation:
X + 2y = 21
A. 4x + 6y = 64
B. 2x + y = 36
C. 4x + y = 21
D. -3x + 4y = 33
E. 3x + 2y = 28
x = 3
y = 9
X + 2y = 21
3 + 2(9) = 21
3 + 18 = 21
21 = 21
A. 4x + 6y = 64
4(3) + 6(9) = 64
12 + 54 = 64
66 is not = 64
B. 2x + y = 36
2(3) + 9 = 36
6 + 9 = 36
15 is not = 36
C. 4x + y = 21
4(3) + 9 = 21
12 + 9 = 21
21 = 21
